Abstract: Objective Exploring the clinical diagnostic effect and patients’ satisfaction of 3D printing reconstruction examination intervention in maxillary sinus wall repair.Methods 52 patients with maxillary sinus wall repair admitted to our hospital from April 2022 to November 2022 were collected as research subjects.52 patients were divided into a control group and an observation group using two different methods: CT 3D reconstruction and 3D printed image reconstruction. Each group has 26 cases.The conventional group was diagnosed using 128 slice CT 3D reconstruction examination,while the observation group was diagnosed using 3D printing images (3DPI) reconstruction examination.Medical staff counted the diagnostic efficacy of each group of patients using different methods,and conducted a survey on the overall satisfaction of patients with diagnosis.Results The scores of masticatory function, language function and retention function in observation group were higher than those in conventional group, and the differences were statistically significant (P<0.05). The satisfaction of the conventional group was 26.92%, and that of the observation group was 80.76%, and there was statistical significance between the two groups (P<0.05).Conclusion The scores of masticatory function, language function and retention function in observation group were higher than those in conventional group, and the differences were statistically significant (P<0.05). The satisfaction of the conventional group was 26.92%, and that of the observation group was 80.76%, and there was statistical significance between the two groups (P<0.05).
